    Anyone use one, know anyone with one, played with one, etc?

    The only major player I'm aware of is www.flex-radio.com . I've been reading their ads, reading their web site, etc and it seems to me that it makes sense to go this route.

    Thoughts / criticisms?

    So do I understand this correct. Software defined radios are just fancy multimode transceivers? The software "defines" what mode the radio operates. So with the same transceiver you could run AM, FM, SSB, RTTY,SSATV, etc. etc. etc...

    Sounds interesting but I don't see it being popular for amateur use at this time.

    the software defined radio is a very neat idea, I think I'd like one, with a linked amplifier and tuner, but boy they are pricey!!!

    I think they appeal more to the contester as you can tune the radio, look at the scope, log, and have a keyer (both voice and CW) running in the same screen while tuning the amp/antenna and spinning your rotor.

    I've played with a friend's setup of a FT 2000 with a computer control, and it does make a little difference when a lot of your log is filled in, all you type in is the call. I would however miss spinning the big dial.

    It looks appealing especially the wide, low-noise receiver.

    I'd spend that much on guns because they hold their value (mostly) but electronics is always depreciating so for me it's too much $.

    A software designed radio will never appeal to the contest crowd. There are too many points of failure.

    Many of the hardcore contesters won't use windows machines, it is strictly a dos world. When you are going for a record or putting in a serious effort, even a couple minutes of down time can ruin an entire weekend. When you are clipping along at a rate of 300-400 QSO/hr, 5 minutes could be catastrophic.

    What percentage of the entire DXer base would you estimate to be hardcore contesters?

    It is strange that they would put that much effort into the product and go with Windows instead of Linux.

    It would seem to me software defined radios would be cheaper, not more expensive than traditional radios. Or at least it should be possible to build one for cheaper.

    My first VCR cost me $450.00

    Give them time, they will come down in price.

    The only reason Windows machines have problems is that they allow idiots to own them.

    I have an XP machine that gives no trouble whatsoever, used heavily. I even had a ME machine (the supposed OS of the Beast) that run fine.
